I took the $$$ plunge into EFI Live about a year and half ago. I'm thinking most members will avoid the expense of OBDII software because of the cost? I keep hoping someone, will provide a low cost "Flash" software for OBDII.

give it time.... i mean, it's been 16 years since OBD2 was introduced, but at one point in time, there were low-cost and free OBD2 tuning options, a lot of which were more or less open source.... but then companies started basically copy/pasting, adding in a couple of small features, and we get to where we are today.

Yea the super high price of obd2 stuff is whats keeping me from using it. Otherwise I would probably be swapping a 411 pcm into my wrangler instead of a 7727. Probably would be looking into a crank trigger and swap my cherokee to the 411 too, if tuning it wasnt so dang blasted expensive. Can we say sequencial and CNP ignition! Just wish the 411 would support CNP ignition in a 6cyl.

So is the FlashScan data really worth $499 ? Ouch... OH! I remember a guy gave me EFI live once.... I wonder if.... no I don't have the cable, just the software...

I haven't used my V2 that often, it's mostly been a high priced tool that doesn't get used much. (BTW I got my EFI Live system used off Ebay at about a 35% savings) My current business model, requires me to make the $125 EFI Live license fee non-refundable... Ouch! There is a small market for custom programming street rod / hot rod / off-road applications where the non-refundable license fee is tolerated. There is a small market for a complete stand-alone Road Runner system, including custom wiring harness. My SBC O411 PCM project has generated interest and new business. The price of a decent used LSx engine is affordable compared to a re-built roller SBC. If you invest the time to build a "Hear it Run" LSx engine on a stand with the Road Runner, you will attact a very different kind customer with a very different budget! A customer with "Steak Dinner" on his mind not a "Fast Food Drive Thru"! The kind of customers who don't get their hands dirty, but know and PAY people that will get their hands dirty!

There are already xdf's for the 411 for TPRTv5. I downloaded a zip file on here that had them in it. (talk about overwhelming ammounts of parameters!)
So if the xdf's have already been made, whats the biggest reason the DIY people arnt using this more? Is it just a lack of a program to DL and reflash the pcm? I just havent been able to understand the whole per vehicle license thing on the software that is currently avalable, other than a way for the company to continue to make you pay for something you have already paid for.

I thought it was done through the ALDL plug?
If people can hac bins, write xdf's, adx's, and someone made a program as uber nice as tunerpro, then I'm sure its only a matter of time before someone makes a program to up and download/flash them, thats afordable, if not freeware.

yeah, it's done through the data link connector, but you need a somewhat beefy processor in the cable to translate stuff between USB and the comm protocall used by the PCM.

the thread on TGO for the 0411 mentions that Dimented24x7 knows someone who is working on something like a command line (DOS) based programming solution, but i have no idea on what kind of cable is required.
